Mayfly16 is large enough to swallow
up three men or maybe a family with two kids. She has
two benches that are 7' long and there should be plenty
of room for all. I would say that her fully loaded maximum
weight might be 900 pounds and her empty weight about
350 pounds, leaving 550 pounds for the captain and crew
and gear.

At the same time the Mayfly16 can easily
be handled solo, athough with just the weight of her skipper
she will not be as stable as when heavily loaded. The
boat also has two large chambers for buoyancy/storage
and I can see her used as a solo beach cruiser because
the floor space is large enough for a sleep spot. I've
made her deep with lots of freeboard.

Mary and George Fulk built the prototype and passed by here on their annual migration north for the summer and I had a chance to see and sail in Mayfly16 for a short bit. Weather was hot and the wind light and steady, perfect for testing. She sailed quite well I thought and everything worked as planned. It certainly was roomy and easy to rig and use.

The balanced lug rig sets on short spars and sails very well reefed, in fact can be set up with jiffy reefing. The spars are all easily made and stowed, the mast being but 14' long setting 91 square feet of sail. In addition there are oar ports for those with lots of time and little money and a motor well for those with lots of money and no time. Two horsepower is all that a boat like this can absorb without going crazy.

The motor well is an open self draining well that uses the full width and depth of the stern. It will come in handy for storing wet muddy things you don't want inside the boat, like boots and anchors. I've suggested in the plans that the rudder can be offset to one side a bit to give more room for the motor. We did not use George's little Evinrude since the boat sailed easily in all directions, but George says the side-by-side sharing on the stern of the motor and rudder works fine. There was no interference with the rudder. (As with any outboard on any sailboat, the motor has a desire to grab the sheet with each tack so you usually have to tend the sheet a bit.)

Mayfly16 uses conventional nail and
glue construction needing six sheets of 1/4" plywood
and two sheets of 1/2" ply.
